Attackers can exploit this flaw to force the server into SSRF requests, coerce NTLMv2 hash disclosure via attacker-controlled SMB shares, and read arbitrary files from the underlying Windows host through an out-of-band error-based channel. WebAdvisor entered end-of-support status in June 2022 and users are encouraged to migrate to Colleague Self-Service.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-611"],"vendors":[],"products":[],"references":[{"url":"https://www.ellucian.com/","tags":[]},{"url":"https://www.vulncheck.com/advisories/ellucian-webadvisor-unauthenticated-xxe-injection","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
